17 NORTHUMBERLAND AVENUE Price Paid vs. HPI Average

The below graph shows the average detached house price in the Buckinghamshire local authority area over time, sourced from the HPI. The three 17 NORTHUMBERLAND AVENUE sales between December 2005 and August 2010 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the August 2006 sale was for 23% below the HPI. So the extrapolation line tracks at 23% below the HPI over time, until the August 2010 sale, where it rises to 8% above the HPI. The line then continues to track at 8% above the HPI.
